I installed Veeam Agent Free on a desktop a few months ago. It was backing up fine for a couple month but the last few days the backups have been failing.

In the Windows logs there is a SQL VSS Writer Error. There's a version of SQL Server installed on the computer. If I stop the SQL service the backup works. I looked at the SQL error logs and I see several lines of this after each time I try to run a Veeam backup.

When you encounter a technical error it's always recommended to raise a support case immediately to get a solution asap, as our ability to troubleshoot through the forum is limited.
